Later this month, “The Voice” judge Blake Shelton will double up as host and musical guest for the Jan. 24 show.

Before their “SNL” appearances, both artists had chart-topping albums. Sia’s “1000 Forms of Fear” made Billboard’s 200 chart. A five-time Grammy nominee, Shelton’s “Bringing Back the Sunshine” debuted at No. 1 on the Billboard 200 chart.
